With a fixed supply of 10 billion tokens and a storage fund that continually takes tokens out of circulation, adoption naturally reinforces scarcity. The more the network is used, the more SUI is removed from circulating supply.
Aside from the refundable portion of storage deposits, SUI in the storage fund is locked indefinitely and effectively removed from active circulation (i.e. burned).
Storage fees reinforce scarcity in three ways:
Non-refundable storage fees are tokens permanently removed from active circulation.
Deposits for mutable objects remain locked as long as the object exists. If the object is modified to require less storage, part of the deposit is returned.
Since immutable objects cannot be changed or deleted, their deposits are never returned, locking those tokens in the storage fund forever.
Because SUI’s supply is capped at 10 billion tokens, these dynamics create steady downward pressure on available supply. As adoption grows and the storage fund expands, this pressure increases, reinforcing SUI’s long-term value.
